z = (x - 500) / 100

1.75 = (x - 500) / 100

175 = x - 500

675 = x

Answer:

A -60i - 14j

Step-by-step explanation:

u = -9i + 8j

v = 7i + 5j

2u = 2(-9i + 8j) = -18i + 16j

6v = 6(7i + 5j) = 42i + 30j

2u - 6v

(-18i + 16j) - (42i + 30j)

(-18i - 42i) + (16j-30j)

-60i - 14j

Tegan needs to make 686868 more snow blocks to finish building an igloo. Write an equation for the number of blocks Tegan still
Keith_Richards [23]

Answer:

We are given:

No: of blocks Tegan still needs to make = m.

No: of blocks Tegan has completed = c

Total No:of more snow blocks need to make = 68 .

Total number of more snow blocks need to make = Total number of blocks -  The number of blocks Tegan has completed.

m = 68 - c.

Therefore, the equation for the number of blocks Tegan still needs to make, m, when she has completed c blocks is

m = 68 - c.

For example.

Suppose if c = 10, it means Tegan still needs to make 68-10 = 58 block.
